As the editor and nominal "publisher" of the MSNS Mich-Matist, I asked the Board of Directors to approve an increase in payments to authors from 5 cents to 10 cents per word, with a maximum of $100. That maximum creates an natural ceiling about 1000 words, which is the right length for the magazine. This puts the Mich-Matist at double the CSNS Centinal, and within range of the ANA's Numismatist. For the ANA "Internet Connections" column, I send in about 900 words and get $120 per issue. For features, say 1800 to 2000 words, such as the recent one on Proof $20 Gold Coins, or earlier efforts on Large Cents, Dime Type Sets, or Sir Isaac Newton, I typically get about $180 to $220, depending on the layout. The ANA pays by the printed page, not by the word.
I have an article coming out in The Celator in October. The Celator pays with an annual subscription. In this case, the 3400 word work garnered a $30 value, under 9 mils (nine-tenths of a U.S. cent) per word -- and that does not count the occasional news feature that I send in.
Of course, we do not get paid to write here, on RCC, etc.
I have been paid to provide content for numismatic websites. Typically, websites pay about half of print, but are content with an re-edited version of something already written, rather than requiring new work. The single largest body of my online content is at Coin Newbies, which I donated to Alison for her site. Much of that came from "Money Talks" radio script submissions that the ANA did not buy. Other articles on Coin Newbies originated with my work for Lloyd Lim's Numismatica, which also was a freebie.
